Feature
Upstream Seal Two-way Valve
VT trunnion mounted ball valve has two seats on both sides. Each seat has springs loaded and make
seat insert contact the ball surface for sealing. So the valve is bi-directional sealing and no limitation
for installation.
Fire-Safe Design API607/API6FA
When the seat inserts are softened and burnt in case of the fire or unusual temperature increase,
the seat retainer under the duty of the spring, which will can prevent internal leak. Meanwhile,
the middle flange,the upper & lower part of the stem will form a metal-metal contact which can
prevent external leak conformed to API6FA or API607.
Stem and Seat Emergency Sealant Injection
The seat ring and the valve stem have a special grease injection valve. In case of the leakage,
the grease will be injected to the valve ball surface and stem room to create a temporary sealing.
Double Block and Bleed
The trapped cavity pressure can bleed out by vent fitting or drain plug when the valve is in
fully open or fully closed position. The fluid is intercepted by seats of up and down stream
side. So the stem packing or O-ring may be replaced under working pressure. Each seat works
independently assuring tight seal against ball on both upstream and downstream side.
